Product Cost: The amount of resources (time and money) required to build the
product one time, correctly. In manufacturing environments, this represents the bulk
of the total costs, often as much as 95%. By contrast, in Information Technology, it
is common for this to represent as little as 30% of the final cost of a product. The
remaining funds expended are the cost of (poor) quality. Some of these costs are to
prevent errors from being created, while others are to catch and correct defects
already built.
